Trees and Shrubs
A division of the Camden Park catalogues that is not clearly defined. In broad terms it includes all plants with woody stems except conifers and fruit trees and shrubs.
Genista anglica L.
Fully-hardy, spiny deciduous shrub, sometimes procumbent, with small but showy, pea-like yellow flowers in spring and early summer. To 60cm. [RHSD, Hortus, Hilliers’].
Genista canariensis L.
Frost-tender, unarmed, broom-like shrub with trifoliate, white-hairy leaves and terminal inflorescences of fragrant, bright yellow flowers. To 2m. [RHSD, Hortus].
Genista canariensis L. var. atleyanus
See Genista canariensis L. for a description of the species. IPNI relates Cytisus atleyanus Hort. ex K.Koch to Cytisus canariensis, with the additional note decumbens, suggesting a prostrate form but I have been unable to confirm this.
Genista canariensis L. var. ramosissimus
See Genista canariensis L. for a description of the type. The variety ramosissimus has shorter and more numerous racemes and the leaflets are smaller and smoother above [RHSD].
Genista canariensis L. var. rhodopnoa
For information on the species see Genista canariensis L. I have found no specific description of rhodopnoa and am unsure if it is worthy of status as a variety or should be considered as a synonym. Cytisus rhodopnoa (Webb & Berthel.) Schouw, the name published in 1847, is given as a synonym of Teline canariensis (L.) Webb & Berthel. by D.J. Mabberley [Taxon, 33(3) p.439/1984]. In this paper Mabberley gives ‘rhodaphne’ as an alternative to ‘rhodopnoa’.
Genista italica Lodd. ex G.Don
Fully-hardy evergreen shrub. To 90cm. [JD].
Genista maderensis (Webb & Berth.) Lowe
Frost-tender evergreen shrub or small tree with silvery young branches, trifoliate leaves and short terminal racemes of up to 12, fragrant, golden-yellow, pea-like flowers. To 6m. [RHSD, Hortus].
Genista stenopetala Webb & Berth.
Fully-hardy evergreen shrub with flattened branchlets, abundant trifoliate leaves, and racemes of yellow flowers. Reportedly to 6m but usually of dwarf habit in gardens and often grown as a pot plant. [Hortus].
Ginkgo biloba L.
Fully-hardy, columnar, then wide-spreading dioecious, deciduous tree with flat, fan-shaped leaves, to 12cm across, turning yellow in autumn, catkin-like male flowers, and solitary female flowers, followed by plum-like, yellow-green fruit, to 3cm long, in autumn. To 30m. [RHSE, Hortus, Hilliers’].
Gleditsia frutescens [Macarthur]
Frutescens means shrubby, bushy [Stearn] and Gleditsia frutescens is probably a shrubby variety, possibly a nursery name for a garden variety of one of the commonly grown species described here. Perhaps the most likely is Gleditsia sinensis Lam. var. nana, syn. Gleditsia nana Hort. ex Dippel, a dwarf form probably introduced to cultivation between 1840, when Paxton’s Dictionary was originally published, and 1849 when a second edition was published with a supplement.
Gleditsia japonica Miq.
Fully-hardy, formidably armed tree with flattened thorns to 8cm long, pinnate leaves, and fruits to 30cm long, often twisted at maturity. To 20m. [RHSD, Hortus, Hilliers’].
Gleditsia sinensis Lam.
Fully-hardy medium-sized tree with branched spines, fern-like, pinnate leaves, and racemes of small, green-white flowers, followed by straight, flat but thick fruits, to 25cm long. To 12m. [RHSD, Hortus].
Gleditsia triacanthos L.
Spreading, deciduous tree with a spiny trunk and shoots, the spines branched and up to 15cm long. It has pinnate leaves, to 25cm long, composed of up to 24 leaflets, and pendant, sickle-shaped seed pods, to 45cm long, in summer and autumn. To 30m. [RHSE, Hortus, Hilliers’].
Glycine backhousiana Lem.
No description at present. Listed in Johnson’s Dictionary and Paxton’s Dictionary, but no details given other than that it is a tender evergreen climber.
Gmelina asiatica L.f. var. parvifolia (Roxb.) Moldenke
Frost tender, often spiny shrub with ovate leaves, to 6cm, and slightly pendant terminal racemes of yellow flowers. To 10m. [RHSD].
